Effect of valve overlap and compression ratio on variation of measured performance with exhaust pressure of aircraft cylinder and on computed performance of compound power plant

Carroll S. Eiannaca-tn-2025Feb 1950

An investigation was conducted on an aircraft liquid-cooled single-cylinder test engine (four-stroke-cycle spark-ignition type) equipped with direct fuel injection to determine the effect of valve overlap and compression ratio on variation of engine power and specific fuel consumption with exhaust pressure.
